A surveyed of the extent of presence of heavy metals in bore-hole water sources in Borno South using Biu, Bayo, Huwul, Kwaya- Kusar and Shani local Government councils as case study was carried out whereby sample of Bore-hole water was fetched from the capital cities of the area council respectively and was taken for analysis in Laboratory using ED-XRF spectrometer and from the result it was found that the following metals Fe, Cu, Hg, Cd, As, Pb,Zn and Cr were present. Evidentially it was revealed that the concentrations of some of these metals is above the limit permissible according to WHO 2008 while some is low, In further analysis, the anticipated health implication were considered by computing the chronic daily intake (CDI), hazard quotient (HQ, hazard index (HI) and carcinogenic risk (CR) of some of the metal to ascertain the threshold level on the intake and make inference on the gross toxicological implications and carcinogenic risk likely to result from the continual intake of the metals into the body systems over a long period no matter how small and so inference is made on the health risk implication for the populace.
